Abstract
New measurements have been made of the melting parameters (pressure-temperature coordinates of the melting curve and change of volume) of nitrogen and argon up to 5500 kg/, and the latent heat of melting has been calculated from them. The qualitative behavior of these parameters is exactly like those of all other normal substances (with rising melting curves) hitherto measured, so that there is no experimental basis for the expectation of a critical point between liquid and crystalline phases, or of a maximum or of an asymptotic temperature, but all the experimental evidence indicates only a rise of the melting curve to indefinitely high temperature and pressure.
